obd reader, oil pressure

[carew]

Can anybody tell me if obd readers do oil pressure.

Also is it worth getting an oil cooler.

My cars going in for an oil change next week. Having a flush done, sump taken off, new oil pick up pipe installed. So was wondering whether to get an oil cooler fitted.

OBD readers generally do not do oil pressure as a continuous function i.e. in psi. This is partly because very few cars actually have a pressure sensor that reads the value. As well as that, it is not a value that needs monitoring to control engine running or emissions (beyond the simple good/bad sense). Nearly everyone has a low pressure switch, which obd readers will check, but I don't think that is what you are after.

Thanks for the reply mate.

So the only real way of doing it is with a gauge.

I just remember on my dad's lanciq intergrale having the gauges.

Would it be worth getting the oil pump done? What's the average life of or? Would people replace it as a means of caution?

My Leon has done 98k on the original pump.

thanks

I've never changed an oil pump on any car or motorcycle I've owned, and some have done long service. They work under constant copious lubrication so there is very little wear. The only time you might look at one is if you've had a bearing fail or some other incident that has got swarf or dirt into the oil - even then a good clean is usually enough, after inspection.

I won't say that you should not change it, and I don't think it is a difficult job. What *is* a good idea is to inspect the strainer that sits on the bottom of the pump and clean any debris off of it. They sometimes get clogged - usually with bits of sealer from the sump joint. If too much is applied, when the bolts are tightened down the excess gets squeezed out and forms a bead or droplets on the inner face of the joint. These cook, break off, and clog the sump strainer.
